Trying for baby #2...

So I am on cd 26 and my glow and Ovia says af is due the day after tomorrow. My boobs are a little sore, not too awful. I have the worst headache (have had it for 2 days.), and I am so constipated (had that with my first pregnancy [MC at 5w4d] and then had it when I got pregnant with my LO who is now 19 mo.) I am very tired and last night I got so nauseous I had to lie down for a bit, and I haven’t been that sick since I was pregnant with my son (had morning/all day sickness with him from about 5 wks pregnant up until the hour before I gave birth to him...no lie) anyway I never chart my bbt, only my cm and cp and my cp has been low and soft. My cm went from ew at O time and then went to like water, then to glue like, now it’s been like this for the past 4 days there’s not a huge amount but enough for me to feel wet, if that makes sense? Also I have what feels like pressure in my lower abdomen...it’s not painful, I can just feel it. Anyway, I took a test on cd 21 and 23 (too early I know) I thought I seen a line one the 2nd one but I think it was an evap. Am going to test with my fmu in am on cd 27, Ovia is saying I can test today but I think I’m going to wait til tm. Any help or advice or what you glow sisters think would be so appreciated ☺️
